Frozen tunas lay on the floor before being auctioned at Tsukiji market in Tokyo, Japan, on November 11, 2006. The Tsukiji fish market is the biggest wholesale fish market in the world. Because of the problems they cause, tourists were banned from the tuna auctions during the period between 15 December 2008 and 17 January 2009. Since, the market reopened to tourists with new rules prohibiting flash photography. Photo by Lucas Schifres/Pictobank
